/// 5.8 Event Tracker Response Object

/// wishes to track and the URLs/information to track them. Bidder must only respond with methods
/// indicated as available in the request. Note that most javascript trackers expect to be loaded at
/// impression time, so it’s not generally recommended for the buyer to respond with javascript
/// trackers on other events, but the appropriateness of this is up to each buyer.
